Bandeirantes
Bandeirantes (Portuguese: [bɐ̃dejˈɾɐ̃tʃis]; lit. 'flag-carriers'; singular: bandeirante) were frontiersmen and explorers in Colonial Brazil who, from the early 16th century, participated in inland expeditions to find precious metals and enslave indigenous peoples. They played a major role in expanding Brazil's borders to its approximate modern-day limits, beyond the boundaries demarcated by the 1494 Treaty of Tordesillas.
